Answer & Solution
Correct Answer
(B) \(2\)
Step-by-step Solution
Detailed explanation
Given mass of solute \((w)\,=\,120\,g\) mass of solvent \((w)\,=\,1000\,g\) Mol. mass of solute \(=60\,g\) density of solution \(=\,1.12\,g/ml\) From the given data, Mass of solution \(=\,1000+120=1120\,g\) \(d=\frac {Mol.mass}{V}\) or \(V=\frac {Mol.mass}{d}\) Volume of…
